Diagram in the front panel with similar distribution that the elements in the real unit. Steel box. In this unit, the elements are separated in two parts: lefthand part for analog to digital conversions, and right hand part for digital to analog conversions. Analog/ Digital converter board. Digital/ Analog converter board. Signal generator board, with 100 to 330 mF capacitors, 10 to 50K potentiometers and 1 to 100K resistors. Female and male connectors, interconnections. Power supply. LPF-Low Pass Filter: 2nd order low pass filter, needed to convert analog signals to digital. Adding: this module makes sum of two analog signals. Sample/ Hold: this module holds the signal during the conversion. The input is E, and the output is S. The digital S/ H control input defines the operation mode: hold or sample. Comparator: inputs E+ and E- are compared, and give the result in the digital output S: if E+ > E-, S will be at high level. The gate OR inverts the input IN, to finally give the result of bit operation OUT= S+ NOT ( IN) . Clock: this module generates two digital clocks, CLK1 ( 245 Hz) and CLK2 ( 250 kHz) .
